MR assessment of oral cavity carcinomas

Magn Reson Imaging Clin N Am. 2012 Aug;20(3):473-94. doi: 10.1016/j.mric.2012.05.003. Epub 2012 Jul 3.

Abstract

Approximately half of head and neck carcinomas arise from the oral cavity. Imaging plays an essential role in the preoperative evaluation of oral cavity carcinomas. MR imaging is particularly advantageous in the evaluation of the oral cavity, with better depiction of the anatomy in this region and reduction of dental artifacts compared with CT. MR is also the preferred imaging modality for the evaluation of bone marrow invasion and perineural tumor spread, which are findings critical for treatment planning. Advanced MR imaging techniques may potentially better delineate true tumor extent, determine lymph node metastases, and predict treatment response.
